posi rear info request
a friend just got a complete leaf spring rear axle [i have a coil spring rear] with a posi [ratio unknown].
i would like to have a posi in my '67 C-10 panel. i have a 3.73. how many different series posi units are there? what are the ratio ranges of each. point is if this were to be a 3.08 [or whatever is the close #] would the 3.73 work. same for a 4.10.
thanks rod in AZ
